AXLE-LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 409,573, dated August20, 1889.

Application filed May 20, 1889.

To aZZ whom it may concern:

Be it known that I, HENRY M. GOODMAN, a citizen of the United States,and a resident of Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in SelfOiling Axles; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawing, and to letters or figures ofreference marked thereon,which forms a part of this specification.

The figure of the drawing, is a central 1011- gitudinal section.

This invention relates ,to axle-lubricators; and it consists in thenovel construction and combination of parts, as hereinafter specified,and pointed out in the claim.

In the accompanying drawing, the letter A designates a Wheel-hub,through which is longitudinally disposed a metallic tubular boxing B forthe spindle O of the axle.

D is a metallic cap having threaded opening 6 for the introduction ofoil, and a threaded plug f, having a vent g, to close said opening. Thecap D is internally threaded and is pro vided Wit-h an internal annularshoulder h, which abuts against the annular rim 2' of the circularthreaded flange-extension E of the boxing B when the said cap is screwedcircumferentially on the said extension. An oil space or reservoir G is,thus formed between the cap and flange-extension E.

The boxing B is continued out at it, projecting beyond the vertical wallI of the extension E into the oil-reservoir G, and terminates in anannular flange m at about the middle of said reservoir. In rear of saidflange through the boxing Bis provided a circularfunnel-shaped openingat for the passage of the oil to the spindle O. This spindle is providedwith a circumferential or longitudinal groove 8 for distributing theoil, and said groove is extended to provide a rear outlet z for theescape of any excess of oil. The end of the spindle is provided with theusual fastening-nut N, which is screwed'down A washer V is interposedbetween the collar H of the axle and the ring-plate R to prevent unduefriction of the collar. When the lubricat-or is in use, the reservoir Gis about half full of oil, and the revolution of the wheel-hub causes anoccasional drop or two of oil to fall in the funnel-shaped opening a ofthe box-extension, through which it passes into the grooves of spindleO, whence it is distributed throughout the boxing, any excessof oilescaping by the outlet 2 in rear of the spindle. The cap D of thereservoir G also serves to prevent loss of the axle-nut if the lattershould work loose on the spindle, and also prevents the entiredisengagement of the hub from said spindle.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

The combination, with a grooved axle-spindle, of a hub having a boxingsurrounding the inner bore of the hub and formed with a verticalextension inward a short distance from its outer end extension, whichouter end extension has a lubricant-aperture, while said verticalextension has a horizontal peripheral extension fitted with a chamberedcap, and the said outer end extension has fitting against it a capscrewed upon the axle-spindle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY M. GOODMAN.
